Question

What happens in C if we do something like this in Java:

    temp.next = temp.next.next;

What will happen to temp.next node? In Java there is a dump/ garbage collector; is there something similar in C?

Answer 1

Nothing will happen to it. It will continue to use memory and you will have lost any means to use it or free it.

In C you have to explicitly free stuff you obtained via malloc when you’re done with it, there’s no such thing as reference counting or garbage collection.
